When a C*-algebra is a coefficient algebra for a given endomorphism [PDF]

arXiv, 2005
The paper presents a criterion for a C*-algebra to be a coefficient algebra associated with a given ...

A Cuntz--Krieger uniqueness theorem for semigraph $C^*$-algebras [PDF]

arXiv, 2011
Higher rank semigraph algebras are introduced by mixing concepts of ultragraph algebras and higher rank graph algebras. This yields a kind of higher rank generalisation of ultragraph algebras. We prove Cuntz--Krieger uniqueness theorems for cancelling semigraph algebras and aperiodic full semigraph algebras.

You Can See the Arrows in a Quiver Operator Algebra [PDF]

arXiv, 2003
We prove that two quiver operator algebras can be isometrically isomorphic only if the quivers (=directed graphs) are isomorphic. We also show how the graph can be recovered from certain representations of the algebra.

Operator algebras: an informal overview [PDF]

arXiv, 2009
In this article we give a short and informal overview of some aspects of the theory of C*- and von Neumann algebras. We also mention some classical results and applications of these families of operator algebras.

Indecomposable characters of infinite dimensional groups associated with operator algebras [PDF]

arXiv, 2013
We determine the indecomposable characters of several classes of infinite dimensional groups associated with operator algebras, including the unitary groups of arbitrary unital simple AF algebras and II$_1$ factors.

Operator algebras associated to modules over an integral domain [PDF]

arXiv, 2016
We use the Fock semicrossed product to define an operator algebra associated to a module over an integral domain. We consider the $C^*$-envelope of the semicrossed product, and then consider properties of these algebras as models for studying general semicrossed products.

Multipliers between two operator spaces [PDF]

arXiv, 2003
In a recent survey paper we introduced one-sided multipliers between two different operator spaces. Here we give some basic theory for these maps.

Pseudodifferential operators and weighted normed symbol spaces [PDF]

arXiv, 2007
In this work we study some general classes of pseudodifferential operators whose symbols are defined in terms of phase space estimates.

Commutants of von Neumann Correspondences and Duality of Eilenberg-Watts Theorems by Rieffel and by Blecher

, 2005
The category of von Neumann correspondences from B to C (or von Neumann B-C-modules) is dual to the category of von Neumann correspondences from C' to B' via a functor that generalizes naturally the functor that sends a von Neumann algebra to its ...
